NetBackup 4.5 Troubleshooting Guide for Windows Media and Device Management Process Media Manager Functional Description When the Media Manager daemons are running, NetBackup, Storage Migrator (UNIX only), Storage Migrator for Microsoft Exchange (Windows only), or other users can initiate data storage or retrieval by sending a request for the required media ID to the Media Manager device daemon, ltid (Figure 14). ltid determines the location of the requested media ID by sending a query to the Media Manager volume daemon, vmd. The volume daemon then returns the information it has about the media, including: robot number, robot type, host, slot, and barcode. If the media is in a robot, ltid sends a mount request to the robotic daemon that manages the drives in the robot that are configured on the local host. The robotic daemon then chooses an available drive, mounts the media, and sets a drive busy status in memory shared by itself and ltid. If it receives another mount request, ltid checks that status to determine which (if any) drives are available. Drive busy status also appears in the Device Monitor. Assuming that the media is physically in the robot, the media is mounted and the operation proceeds. If not a NetBackup backup job and the media is not in the robot, ltid sends a mount request, which appears as a pending request in the Device Monitor. An operator must then insert the media in the robot and use the appropriate Device Monitor command to resubmit the request so the mount request can occur. For a NetBackup job, if the media is not in the robot, ltid sends a mount request which is then canceled once the media is determined to be missing and another volume is selected to be mounted. A mount request is also issued if the media is for a nonrobotic (standalone) drive and the drive does not contain media that meets the criteria in the request. If the request is from NetBackup and the drive does contain appropriate media, then that media is automatically assigned and the operation proceeds. See the NetBackup System Administrator’s Guide for more information on NetBackup media selection for nonrobotic drives. Note When a tape is being mounted, the drive_mount_notify script is called. This script is in the /usr/openv/volmgr/bin directory. Information on the script can be found within the script itself. A similar script is called for the unmount process (drive_unmount_notify, in the same directory). When a robotic volume is added or removed through the media access port, the media management utility communicates with the appropriate robotic daemon to verify the volume location and/or barcode. The media management utility (through a library or command-line interface) also calls the robotic daemon for robot inventory operations.
